Cold Bullet - Brittle and Ashe, #3

Bounty hunters Charlie Brittle and Owen Ashe ride into Worthwhile, Missouri expecting to collect the money owed them and then continue on their way. But when Charlie finds himself unexpectedly charmed by brothel owner Lady Gracie, he and Owen end up taking her side in a feud with a rich and powerful cattle baron named Dunwoody. Dunwoody wants Lady Gracie gone, no matter how he has to do it. To that end he's hired a small army of gunslingers to carry out his dirty work.
Among them is a dark figure from the past who longs for the coming showdown, and a chance to put a cold bullet right through Charlie's heart.
